I love to shoot panoramas, with my DSLRs and my iPhone - it's a great way to capture the feeling of a big landscape.  This is one of my recent favorites, a view of the Errara Channel, on the west coast of the Antarctic Peninsula, from the summit of Danco Island.  The little bump in the far right is Cuverville Island.
